INSOLE MACHINE.

Application led July 5,

To all whom t may concern:

Be it known that I, JOHN B. HADAWAY, a citizen of the United States, residing at Swampscott, in the county of Essex and State of Massachusetts, have invented certain new yand useful Improvements in Insole Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artv to ,which it appertains to make and usethe same.

The present invention relates to machines for operating upon insoles and more particularly to machines of this character-employed in connection with the manufacture of insoles having a fabric reinforcement applied thereto.

It isfdesirabl'e that in insoles of this type and especially what are known as Gem insoles the fabric shall be trimmed while or after applying the reinforcing material in such a manner that it is not exposed after the insole is subsequently incorporated in a boot or shoe.

One object ofthe present invention, accordingly, is to providey certain improvements in insole reinforcing machines to facilitate and increase the efficiency of the fabric trimming operation.

W'ith this object in view the several features of the invention consist in certain novel features of construction, combinations and arrangements of parts hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art from the following description.

In the accompanying drawings illustrating the preferred form of the invention, Figure 1 represents a side elevation of a machine embodying the several features of the invention; Fig. 2 is a front elevation, partly in section, of the machine shown in Fig. 1'; and Fig. 3 is a detail illustrating an elevation, partly in section, of the mechanism for feeding the trimming knife. f

The illustrated embodiment of the inven- Vtion is conveniently applied to the machine disclosed in the patent to Hadaway No.

614,860, November 29, 1898, and certain essential parts of the present machine are idensole.

1919. Serial No. 308,855.

support is rotated intermittently, tofeed'thel work, through a ratchet wheel 14C and driving pawl 16. The driving pawl isoscillated at predetermined intervals, from. a feed lever 17 fulcrumed at 15and having a cam roll 1S upon the upper end which is received in a cam path formed in the face 19 of the usual cam disc 20. This feed lever is connectedto the driving pawl through fa horizontal bell crank 22 having one arm which. is operatively connected with the lower end ofthe Vfeed lever through intermeshingv gear segments 23 and a second arm pivotedto a link v former 33 which completes the molding of the reinforcing fabric in the vusual manner. All of the above described partsv of the machine, together with the mechanism for operating them, are'identical with thoseshown in the patent hereinbefore referred to and in consequence have been only briefly described.

It is an important desideratuml in machines of this character that the reinforcing fabric shall be trimmed during its applicav tion to the insole to conform generally tov the outline of theinsole and in such a manner that the fabric shall be cleanly severed along the desired yline without liability of subsequent exposure when the insole is incorporated in a boot or shoe.` To avoid any possibility of the fabric later showing in the shoe, mechanism has been' constructed for trimming the fabric along a line within the outer margin of the insole and thepresent invention contemplates the improvement of this trimming mechanism to-ensure the proper trimming of the fabric without interference with the application ofthe fabric to the insole'or damage to the bodyof the in- To this end a single rotaryltrimming knife is arranged in' operative relation to the feather of the insole when the insole is positioned upon the work support and is connected with the feedingmechanism to trim the fabric during the return movement of the feeding foot while the ,sole is clamped in a stationary position. The lateral position of' this trimming knife is gaged by the feeding foot and in suoli a manner that the fabric is trimmed at a uniform distance from the base of the lip, thus ensuring that a sufhcient amount of fabric remains to properly reinforce the lip. As shown in Fig. l, a cutting disc 40 is` mounted upon the end of a shaft, 42 journaled in bearings formed in a carriage 43. The carriage 43 is supported at opposite ends upon studs 45 and 46 mounted in the lower ends of arms 47 and 48. These arms are supported at their upper ends upon studs 49 and 50 and the arm 48 is provided with an upwardly extending boss 52 which is engaged upon opposite sides by adjusting screws 53 and 54 threaded, respectively, in stationary lugs 55 and 56. By varyingthe relative positions of ,Y the two adjusting screws 53 and 54, the knife may be shifted laterally and caused to assume the proper operative position relative to the feeding foot 32 so that the fabric is trimmed upon a line immediately back of the feeding foot and at a uniform distance from the outer face of the insole lip. The knife is continuously' rotated during the operation of the machine by the driving shaft 60 having a hub 6i se- `cured to the inner end and provided with a radial slot 62 which receives a rib 63 secured to the shaft 42, as shown clearly in Figs. l and 3. This construction serves to rotate the knife shaft 42 and still permits axial and transverse adjustments of thil knife shaft relative to the drive shaft 60.

Since the knife 40 is located above the table 10, aperipheral groove 64 is provided in the face of the table within which the rotating knife may enter when no work is in the machine and the table rises, under the influence of its spring within the bracket ll, and approaches the stationary former 33. This groove is indicated by dotted lines in j Fig. 2.

The cutting movement of the knife in the line of feed is preferably imparted dur ing the return movement of the feeding foot 32, that is, while the sole is held clamped between the work table and the stationary former. To this end the table feed lever 17 may conveniently -be used as the actuator for the knife carriage 43, the stroke of this lever which moves the feed pawl 16 backward being employed to movel the rotatig knife to the right (Fig. 2) with. he feeding 'foot- 32 which is given a four-motion movement by mechanism connecting it with cam paths in the cam discs 68 and 69, all as described in said patent hereinbefore referred to. Accordingly the lower end of the table feed lever 17 is connected with the knife carriage 43 through a cross link 65 connected at its opposite ends to kthe two members i through ball and socket joints indicated at 66 and 67. It will be noted from an inspection of Figs. 2 and 3 that the studs 45 and 46 upon which the carriage 43 is mounted f are elongated to permit ytransverse slidingmovements of the carriage thereon. With this construction the cutting disc 40 isy caused to move in unison with the feeding movements of the foot 32. Upon the advancing movement of the foot 32 to feed the j work the disc moves therewith and no extension of the cut through the fabrictakes place but upon the returnl movement of the foot, while the work is held stationary,jthe cutting, disc 40 travels through the fabric and trims it upon a line within the edge of the sole. i

In order to accurately ygagethe depth of cut made by the knife so that the latter shall cut through` the fabric without cutting into and thus weakening the leather, the stud 45, upon which the forward end of vthe carriage is supported, is provided with an eccentric portion, asl indicated in Fig. yl, lwhereby when the stud is turned, the knife is raised orkjlowered slightly with relation to the work ta e. t

It will be recognized yby those skilled in the claims, and may be changed or modified without departing from the broader features of the invention. Y
